Isometric

Description

Playfield is technically two-dimensional, but drawn using an axonometric projection, so as to look three-dimensional. Movement input is usually diagonally-biased to match the player's orientation (as opposed to straight up/down/left/right movement, which matches the game avatar's orientation).

While the perspective term has traditionally been labeled isometric, in typical use it includes isometric (e.g. Knight Lore, the Immortal), dimetric (e.g. SimCity 2000, Diablo), and trimetric (eg. Fallout/Fallout 2, SimCity 3) projections.
